Hi there! We flip/cross multiply when our target is found in the denominator. When our target is already in the numerator, just eliminate the denominator.

In the previous question, you took the equation attempting to find a, you flipped the equation. Why did we not flip the equation to find the angle of B in this equation?

Disregard, I tried to solve the previous equation by cross multiplication and got the same result.
